Prospect theory proposes the hypothesis that people have diminishing sensitivity in valuing increases in the size of monetary outcomes, for both gains and losses. For decision-making under risk, this implies a tendency to be risk-tolerant over losses while being generally risk averse over gains. We offer a neurochemistry-based model of the diminishing valuation sensitivity hypothesis. Specifica...

The electromagnetic losses and shielding efficiency of shields for a buried three phase high voltage cable are studied for several shielding configurations. The shields are U-shaped gutters covered with plates, and the power cables are positioned either in trefoil or in flat configuration. The shielding efficiency and the losses are compared for shields with the same geometry but several shield...

Arid zone, ephemeral rivers are characterised by discharge decreasing downstream in the lower reaches due to transmission losses. Modelling the flow regime of these rivers requires data on the spatial and temporal distribution of transmission losses in these reaches. In this study, a hydrological model is developed for a 330 km reach of the Diamantina River in southwestern Queensland, where the...

In this study, we conducted rainfall simulation experiments in a cool desert ecosystem to examine the role of biological soil crust disturbance and composition on dissolved and sediment C and N losses. We compared runoff and sediment C and N losses from intact latesuccessional dark cyanolichen crusts (intact) to both trampled dark crusts (trampled) and dark crusts where the top 1 cm of the soil...

The present work deals with the potential of olive mill wastes as a C source for soil C sequestration strategy, which is based on the high lignocellulosic content that makes these wastes to degrade slowly during composting and after land application. A C balance was performed during the whole life cycle of two different two-phase olive mill wastes (TPOMW): C losses were calculated during the co...

We measure the earnings and welfare losses experienced by displaced employees of the Ecuadorian Central Bank (BCE), and link these losses to individual characteristics such as age, gender, education, seniority and wage in the public sector. Data are from a survey of BCE employees we ran fifteen to eighteen months after separation, including subjective evaluations of well-being in addition to in...

Bovine viral diarrhea virus (BVDV) is a common pathogen of cattle herds that causes economic losses due to reproductive disorders in breeding cattle and increased morbidity and mortality amongst infected calves. Our objective was to evaluate the impact of BVDV spread on the productivity of a beef cow-calf herd using a stochastic model in discrete time that accounted for (1) the difference in tr...

The objective of the study was to monitor the filling and emptying of bag silos at three research farms to determine the variation in density and losses in pressed bag silos. Twenty five bags were filled over the 2000 harvest season, and 15 of those bags have been completely emptied. Dry matter (DM) densities in alfalfa silages were approximately 200 kg/m when the crop was at 40% DM, and densit...

The production of food is responsible for major environmental impacts. Bearing this in mind, it is even worse when food is lost rather than consumed. In Switzerland, 46% of all processing potatoes and 53% of all fresh potatoes are lost on their way from field to fork. Our study therefore compares the environmental impacts of losses of fresh potatoes with those of French fries. With the aid of a...

A decision model to aid in selecting treatments for weaned pigs was developed and tested, with the purpose of reducing nursery mortality and improving weight gain. Interventions evaluated were to not treat pigs, to treat the whole population, or to treat only a subgroup of pigs below a certain weaning weight (target treatment). Outcome was characterized as death or survival. Losses were set at ...
